PurposeThis study aims to explore the dimensions of perceived value of tourists with disabilities at heritage sites. Second, it examines the differences in the precedents of satisfaction and loyalty among tourists with disabilities in two different World Heritage Sites (WHS).Design/methodology/approachThe sample consists of 150 and 184 questionnaires given to tourists with disabilities in Ecuador’s WHS of Quito and Cuenca, respectively. To test the hypotheses, data were analysed using confirmatory factor analyses and structural equation modelling.FindingsThis study suggests a five-dimensional structure for perceived value of tourists with disabilities in WHS. However, differences in the behaviour of people with disabilities are found depending on the specific WHS. While the perceived value factors that determine satisfaction are different according to the WHS, the loyalty precedents remain the same.Practical implicationsThis study contributes to the formulation of actions and strategies towards a more sustainable and inclusive future, where all tourism stakeholders in WHS have role. By understanding the behaviour of tourists with disabilities, these stakeholders will be more informed about the destinations’ elements that need to be improved and enhanced to satisfy this loyal market segment.Originality/valueAlthough the importance of accessible tourism is widely recognised, there is a dearth of literature investigating the behaviour of tourists with disabilities in heritage destinations. This study proposes a model to understand the role of perceived value in cultural heritage destinations.
